In 2420, the earth changed a lot: no more sky, no more river… Luke and his friend are led to discover a “mysterious box” dating from 2008…Luke slowly wakes up from his sleep. Are his parents and the little “plague” still asleep? Difficult to know now. He opens one eye and sees that there is total darkness, and he cannot hear the sound from the outside world. The water in which he floats is at the same temperature as his body and he feels neither heat nor cold. He’s fine, but a little worried. He thinks back to the strange dream of that night.
